Abstract: Uranium contaminated soil treatment is a hot issue in uranium mine environmental management. Phytoremediation technology is a new method dedicated to the remediation of heavy metal pollution in soil. The study of uranium concentration in plants is the focus of phytoremediation of uranium contaminated soil, and it is particularly important to screen plants with strong concentration ability. By investigating the concentration plants under different soil pH values and soil organic matter content conditions, germplasm resources of high-quality uranium-concentrated plants can be obtained. At the same time, it can be combined with soil amendment, plant-microbe remediation, and inter-cropping remediation methods to improve the plant′s ability to concentrate uranium. The research results show that Cyperaceae, Poace, Malvaceae, Brassicaceae, Asteraceae, and Commelinaceae perform well in uranium concentration and can be used as germplasm resources for uranium-concentrated plants.
